2002 GMC Envoy Recalls, Problems & Maintenance

The 2002 GMC Envoy has no open NHTSA recalls. Owners report 7 recurring issue clusters, led by “Fuel odor and leaks at fuel pump, tank and filler neck.” GMC trucks and SUVs use the GM Oil Life System (OLS) — the same algorithm as Chevrolet. Because GMC's lineup is exclusively trucks and SUVs, severe-service intervals apply to most owners (towing, hauling, off-roading). The schedule below surfaces the items most relevant to GMC's truck-focused buyer.

Save this car as:

No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (per Oil Life System)

Every 7,500 mi

Change oil when OLS reaches 0% or every 12 months. dexos1-approved synthetic required on Sierra 1500 5.3L/6.2L; dexos2 specified on Duramax diesel.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate tires every 7,500 miles. Sierra and Yukon owners running 4x4 should rotate every 5,000-7,500 miles to even out drivetrain wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Inspect pads, rotors, and parking brake every 7,500 miles. Towing accelerates pad wear by 30-50%; check more often if towing regularly.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 45,000 mi

DOT 3 brake fluid: test annually, replace when moisture exceeds 3% or fluid is darker than copper.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 45,000 mi

Long-life cellulose filter rated 45,000 miles. Trucks driven on unpaved roads or construction sites should inspect at every oil change.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Automatic Transmission Fluid

Every 45,000 mi

Severe service (towing 5,000+ lbs regularly, heavy stop-and-go): every 45,000 miles. Normal: 97,500 miles. Use Dexron-VI for 6L80/6L90, Mobil 1 LV ATF HP for 10L80/10L1000.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Transfer Case Fluid (4WD)

Every 45,000 mi

On 4WD models, replace every 45,000 miles. Use GM Auto-Trak II for active 4WD; GM 9986115 for selectable 4WD.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

Differential Fluid (front + rear)

Every 50,000 mi

Replace front and rear axle fluid every 50,000 miles, or 25,000 miles if towing. G80 limited-slip rear axles require GM friction-modifier additive.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Spark Plugs

Every 100,000 mi

Iridium spark plugs on the L83/L84 5.3L and L86/L87 6.2L V8 are rated 100,000 miles. AFM/DFM cylinder deactivation can cause uneven plug wear — check at 75,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Dex-Cool Engine Coolant

Every 50,000 mi

Dex-Cool (orange): first change at 150,000 miles or 5 years, then every 50,000. Duramax diesel uses ELC (red) — different chemistry, do not mix.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 22,500 mi

Replace cabin air filter every 22,500 miles. Sierra HD and Yukon XL owners in dusty work environments should replace at 15,000 miles.

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

Fatal crash history & reported problems

driver deaths

117

passenger deaths

4

not recorded by seat

361

occupant deaths

Crash years covered: 1990–2024 This model year first appears in 2001 crashes. Older models have had more years on the road to appear in these crashes, so a higher count here does not by itself mean a vehicle is less safe.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number

FARS 2024 data is an annual report file. NHTSA revises these records when the final file is published, so this count can change.

Why we show driver deaths too

Every vehicle has exactly one driver seat, so driver deaths line up fairly when you compare one model to another. Occupant deaths include passengers, so a three row SUV can show a higher number than a two seat car simply because it carries more people.

Both figures are plain counts, not rates. A rate would need to know how many of each vehicle are on the road, and that registration data is not public, so we do not publish rates or scores of any kind.

IIHS publishes driver death rates using this same driver only idea, paired with a registered vehicle years denominator we do not have. Their rates and these counts answer different questions, so do not read either number here as a safety rating.

Owner-reported problem signals

Separate from the federal fatality data above: complaints owners filed with NHTSA about this year and model. These are reports of problems, unverified, and are counted here only as signals.
